Renal hypoplasia

Disease definition

Renal hypoplasia is a developmental anomaly in which one or both kidneys (unilateral or bilateral renal hypoplasia, respectively (see these terms)) have a deficit in the number of nephrons and may be small. Oligomeganephronia (see this term) represents a severe variant of hypoplasia in which nephron number is reduced by 80% and nephrons are markedly hypertrophied.
